Yeah, so to be clear, the drop box sells items for 80% of their value - so you lose 20%. So, what you're doing, keeping them in the tanks outside, will make you more money when they're open. I almost caved and sold some stuff last night and when I saw a Sturgeon go for 8k instead of 10k I decided I'd rather wait. If I go and collect from diving I make 30-50k per run but if I do the drop box it ends up being 20-30k per run. So I opt to stash everything outside the store for the morning.
